Hi,
Since iOS11.3 I'm getting a significant number of new crash reports from my AR measurement app.
The crash description says:
Exception Type: SIGABRT
Exception Codes: #0 at 0x181b112ec
Crashed Thread: 0
Application Specific Information: *** Terminating app due to uncaught exception 'std::invalid_argument', reason: 'extrinsicTransform must have determinant 1.'
The crash is triggered by this line in my code, which is called on didUpdateFrame
NSArray<ARHitTestResult *> *resultArray = [_arsnView hitTest:position types:ARHitTestResultTypeExistingPlaneUsingExtent | ARHitTestResultTypeEstimatedHorizontalPlane];
According to the crash reporting, it happens to about 10% of the sessions (!!!!). Before iOS11.3, I had <0.1% crashes.
I tried feeding the hitTest with different values for position, including NaN etc, but I'm not able to reproduce the crash.
Any ideas?
Thanks!!
